Spinal cord injury: some epidemiological data. A review of 233 cases.

Two hundred thirty-three consecutive cases of traumatic para- and tetraplegia admitted to a department of Neurosurgery in Naples within ten years were reviewed and categorized according to etiology, level of lesion and clinical features. The age of the patients at the time of injury varied from 7 to 74 years with a mean age of 37.1 +/- 17.1 (male mean age = 35.8 +/- 16.7; female mean age = 41.5 +/- 18.2). The male/female sex ratio was 4.8. Of these patients 66 were paraplegic and 167 were tetraplegic. The analysis of the various causes of the spinal cord injury showed that the occupational activities take the first place (32.2%); injuries in recreational activities and road accidents accounted for the majority of the remaining cases.

Food allergy in preterm infants fed human milk.

In 80 preterms aged 9-24 months (mean age: 15.9) and in 80 sex- and age-matched full-terms the frequency of atopic diseases and of positive skin tests to 8 food and 6 inhalant allergens was determined. The two groups did not differ as to overall percentages of cutipositive subjects and patients with atopic diseases. In particular, frequencies of positive skin tests to foods and of atopic dermatitis (the peak prevalence of which occurs early in infancy) were similar in preterm (16.2 and 7.5%, respectively) and full-term (13.7 and 5.0%, respectively) infants. We suggest that preterm infants fed human milk are not at increased risk of developing food allergy and related diseases and that the absorption of antigens through the immature intestine does not seem to favor the development of an IgE sensitization to foods.

Memory performances after anterior communicating artery aneurysm surgery.

10 patients operated on for anterior communicating artery aneurysm (ACoA) underwent to neuropsychological examination one year after surgery, in order to detect eventual behavioural and/or amnestic disorders, already described by others in a wide percentage of such patients. Even if after accurate neurological examination the therapeutic results were defined as "good", 60% circa of our patients present amnestic and/or behavioural disturbances. Possible correlations between neuropsychological tests finding and intraoperative occurrences (early aneurysm rupture, gyrectomy etc.) are considered and discussed.

Effects of 5 azacytidine on DNA methylation and early development of sea urchins and ascidia.

5-azacytidine (5-azaCR), an analogue of cytidine, inhibits nuclear DNA methylation in early sea urchin embryos. This inhibition is specific and dose-dependent. Exposure of sea urchin embryos at any stage between one-cell and blastula, to micromolar quantities of 5-azaCR invariably inhibits development beyond the blastula stage. In a substantial number of embryos arrested at the blastula stage, spicule formation proceeds although other morphological differentiation is lacking. No significant effect on development is seen if sea urchin embryos are exposed to 5-azaCR at post-blastula stages. 5-azaCR also inhibits the development of a mosaic egg such as the ascidian Phallusia mammilata at the blastula stage, indicating that both regulative (sea urchin) and mosaic (ascidian) embryos respond more or less similarly to 5-azaCR treatment.

Purification and properties of a 3'-phosphoryl former endodeoxyribonuclease from eggs of Asterias forbesi.

A DNA endonuclease has been purified from eggs of Asterias forbesi by a simple four-step-purification procedure. The purified enzyme is at least 96% pure and is free of phosphatase, phosphodiesterase, and RNase. It has a pH optimum of 6.5 and does not require divalent cations. The enzyme produces 3'-phosphoryl and 5'-hydroxyl end groups. The products of exhaustive hydrolysis can be grouped in two fractions. The first fraction, 40%, contains a small amount of mononucleotides and di-, tri-, tetra-, penta-, and hexanucleo-tides. The second fraction, 60%, contains oligonucleotides larger than hexanucleotides.
